Preparative isolation of Heteroclitin D from Kadsurae Caulis using normal-phase flash chromatography
Publikováno v:
Journal of Pharmaceutical Analysis, Vol 3, Iss 6, Pp 456-459 (2013)
Heteroclitin D (H.D) was successfully isolated from Kadsurae Caulis by using flash chromatography and recrystallized by methanol, 10.2 mg of H.D was obtained from 4.86 g of crude extract, and the purity determined by HPLC was 99.4%. The structure was
